Explanation / Answer

In electrochemistry , anode is where oxidation occurs and is the positive polarity electrode in an electrolytic cell.Since Fe2+ has one more electron than Fe3+ it has larger size. Since the mass of the anode has been reduced in amount and we know mass of the atom will be proportional to the size. Therefore Fe3+ will be produced. Also anode is where an element looses electrons.
